the best use would be shoot it in a rifle with a short chamber. shooting it in a lr chamber will result in a carbon ring building up in the chanber. if you shoot very much it can be a real pain to clesn out. also accuracy will usually really suck. think shooting cb shorts in a lr chamber. the bullet has more than an eighth of an inch (.150 plus thou) jump to get to the lands. from my experience you are lucky if you can hit a golf ball at 25yds.
